Question: 174
8. The rectangle below has a length twice as long as its width. If its width is x, its perimeter is
- A. 6
- B. 2x2
- C. 4x
- D. 6x
Correct Answer: D
Explanation:
The correct answer is (D). If the width is x, the length, which is twice as long, is 2x. The perimeter is equal to the sum of the four sides: 2x + 2x + x + x = 6x.
